Trying to setup network for server, but unsure how to edit /etc/hosts

Asked by jbowen7

I've got a home server 9.10 server ed. and I'm trying to set it up as a web server following the guide on http://www.howtoforge.com/perfect-server-ubuntu-9.10-karmic-koala-ispconfig-2-p3, but I'm stuck at editing /etc/hosts. I'm not sure how to edit this file

In it mine has:

127.0.0.1 localhost
127.0.1.1 Server.oc.cox.net Server

# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

the forum suggests this:

127.0.0.1 localhost.localdomain localhost
192.168.0.100 server1.example.com server1

# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

How do I go about configuring this correctly?

Thanks for your help, networking is not my specialty.

What do you need to do with this file?

Basically it's purpose is to translate a human friendly computer address "server1.example.com" into a computer friendly numerical address "192.168.0.100"

you put the IP of the destination first, followed by the human friendly name. 1 IP per line.

I'd expect what you're after is changing the hosts file inside another computer, so that computer can find your server?

Thanks Andy,

Well I wanted to assign my new domain name to my server's ip address.
So would I add (assuming my ip address is 192.168.1.103)

192.168.1.103 www.mynewdomainname.com

or should it be:

192.168.1.103 server.mynewdomainname.com

also must I edited my
127.0.0.1 localhost
to
127.0.0.1 localhost.newdomainname.com

The only consideration here is that my home server is serving two main functions: One hard drive on it is for file sharing on my local network (backup, music, etc.) and I wanted the hostname to be "server"

But the main intention of the server is to host my own websites. This is the first time of set up a server from scratch. I've always been lucky enough to have cpanel or plesk.

use:

127.0.0.1 localhost.newdomainname.com localhost

so that localhost will be resolved to 127.0.0.1 or you will get lots of issues

Can you help with this problem?
